Key Takeaways
  • A faulty brake light switch is a critical safety failure; do not drive if your brake lights are not working correctly.
  • For a 1959 Studebaker 4E1, a new aftermarket switch from a brand like Standard Ignition is the most reliable and cost-effective solution.
  • Replacement of a mechanical brake light switch is a simple DIY task that takes less than an hour.
  • Always check your bulbs and fuses first before replacing the switch.
The brake light switch on your 1959 Studebaker 4E1 is a crucial safety component. It is a simple switch that activates your rear brake lights when you press the brake pedal. On most classic trucks like the 4E1, this is a mechanical switch located under the dashboard, near the top of the brake pedal arm. When you press the pedal, it releases a plunger or lever on the switch, which closes an electrical circuit and sends power to the brake light bulbs. Releasing the pedal pushes the switch back in, opening the circuit and turning the lights off. Its only job is to signal to other drivers that you are slowing down or stopping.

Symptoms of a Failing Brake Light Switch

On a classic vehicle like the 1959 Studebaker 4E1, the signs of a failing brake light switch are straightforward and present an immediate safety risk. You will not get a warning light on your dashboard; a visual check is the only way to know if there's a problem. Before assuming the switch is bad, it's always a good idea to check the simple things first: make sure the brake light bulbs haven't burned out and inspect the fuse.

Key Failure Symptoms

  • Brake Lights Do Not Turn On: This is the most dangerous symptom. The switch has failed internally and no longer completes the electrical circuit when the brake pedal is pressed.
  • Brake Lights Stay On: The switch can also fail by getting stuck in the 'on' position. This will drain your battery when the truck is parked and confuse drivers behind you.
  • Flickering or Intermittent Brake Lights: Worn internal contacts can cause the lights to flicker or work inconsistently when you press the pedal, which is also a safety hazard.

Choosing the Right Aftermarket Switch

For a 1959 vehicle, finding an original equipment (OEM) Studebaker part is nearly impossible. The most practical and reliable choice is a new aftermarket switch. Brands like Standard Ignition (also known as Standard Motor Products) are well-established and produce dependable replacement parts for a vast range of vehicles, including classics. For a simple two-terminal mechanical switch, a modern aftermarket part is often more durable than even a New Old Stock (NOS) part, which can degrade over decades in storage.

Part Type Availability Typical Cost Quality & Notes
New Aftermarket (Standard Ignition) Readily Available $15 - $20 The most common and recommended choice for reliability and value.
New Old Stock (NOS) OEM Very Rare $50 - $150+ Extremely hard to find and primarily for museum-quality restorations. Age can make them less reliable than new parts.
Used OEM Scarce Varies Not recommended due to unknown condition and age. The low cost of a new part makes this a poor option.

Known Issues, Recalls, and Service Bulletins

There are no specific recalls or Technical Service Bulletins (TSBs) from the National Highway Traffic Safety Administration (NHTSA) for the brake light switch on the 1959 Studebaker 4E1. This is normal for a vehicle of this age, as record-keeping was different and many such components were considered simple wear-and-tear items. Some Studebaker vehicles of the era used hydraulic pressure switches that were prone to failure, leading many owners to convert to a more reliable mechanical switch.

Frequently Asked Questions (FAQ)

Is it difficult to replace the brake light switch myself?

No, this is a very easy job for a DIY mechanic if you have a mechanical switch. It is located under the dashboard at the top of the brake pedal. The replacement typically involves disconnecting two wires and unscrewing or unclipping the switch from its mounting bracket. The entire job can usually be done in less than 30 minutes.

How do I know if I have a mechanical or hydraulic switch?

A mechanical switch will be located up by the brake pedal arm under the dash. A hydraulic switch is not near the pedal; it is a small sensor screwed directly into the brake lines, often on the master cylinder or a junction block. If you are replacing a hydraulic switch, the brake system will need to be bled afterward.

Are aftermarket switches as good as the original for a classic truck?

Yes, for a simple part like a brake light switch, modern manufacturing from a reputable brand like Standard Ignition often produces a more durable and reliable component than what was available in the 1950s.

My brake lights are stuck on. Is it definitely the switch?

It is the most likely cause. The switch may be physically stuck, broken, or has failed internally. Also, check that the switch is properly adjusted and that the brake pedal is returning fully to contact the switch's plunger. An improperly adjusted switch can cause the lights to stay on.

Technical Specifications

The replacement part is typically a 2-terminal mechanical switch activated by the brake pedal arm.
